'APPARATUS FO-R THE TREATMENT OF SEWAGE.

SPECIFICATION forming part of Letters Patent No.32.8,334, dated October 13, 1885.

Application filed November G, 1884. Serial No. 147,293. (No model.) Patented in England May 3, 1884, No. 7,198.

To aZZ whom it may concern:

Be it known that weLSAMUEL KILPIN PAGE, of Aylesbury, in the county of Buckingham,

A England, CHARLEs EDWARD ROBINSON, of Scarborough, in the county of York, England, and WILLIAM STEVENS, ofN ew Bridge Street,

in the county of Middlesex, England, subjects of the Queen of Great Britain, have invented Improvements in Apparatus for use in the Io Treatment of Sewage, andin other operations in which solid matter is required to be added to or mixed with duid matter in certain relative proportions, (for which we have made application for Letters Patent in Great Brit- I5 ain, No 7,198, dated May 3, 1884,) of which the following is a specification.

Our invention consists of the improvements hereinafter described in apparatus for use in the chemical treatment of sewage bythe l 2o addition thereto or mixture therewith of solid matter in powder or in a moderately-fine state of division, and for use in other operations in which solid matter in a like state is required to be added to or mixed' with fluid 2 5 matter Vin certain relative proportions; and the object of our said invention is to cause the dow of the sewage or other fluid to which the solid matter is to be'added, or with whichit is to be mixed, to actuate apparatus by which the 3o latter is supplied or by which its supply is controlled. The mixture of the said matters, or the addition of the one to the other, is thus effected automatically.

According to our said invention we mount 3 5 a vessel of suitable form on pivots or trunnions in such a positionrelatively to the mouth of a pipe or conduit whence the duid issues that the fluid so issuing shall pass into the said vessel; and we so arrange or counterbalance 4o the said vessel that when it has received a certain quantity of fluid it will turn on its pivots or trunnions and discharge the fluid it `has received and return to its original position,

, ready to receive another charge of t-he duid. Above the said vessel we mount a hopper, in

which the solid matter to be mixed with or added to the duid is placed, and in the lower part of the said hopper we arrange mechanism by which the discharge or passage of the solid matter therefrom is effected, or regulated or controlled, which mechanism is connected with the tilting vessel, and is actuated by the motion thereof.

We will describe our invention-with refer-4 ence to the accompanying drawings. The same letters and gures of lreference indicate the same parts in each of the figures of the said drawings. Figures 1 and 2 are elevations taken at right angles to each other, and Fig. 3 is a plan of apparatus constructed according to our invention. Fig. 4 is a separate View of part of the said apparatus, hereinafter referred to.

'A is thetilting vessel, mounted on pivots or trunnions a a2, Working in bearings b b, carried by uprights B B, supported by a base or frame, C.

D D are weights adj ustably mounted on arms or levers d d', secured to the said vessel A. of the said levers rest when the said vessel is in the position shown in the drawings, which is its normal position.

E is the hopper, supported above the vessel A by the uprights B B.

The mechanism by which the discharge of the fmatter containedin the hopper is effected, or by which the passage of the said matter is regulated or controlled, consists of a screw, F, the shaft or axis of which passes throughthe sides of the hopper and projects therefrom at one end, as shown in Fig. 4, which is a section of the hopper taken on the line V1, Fig. 3. The said shaft has axed to its projecting end a ratchet-wheel, f', and has a lever, f 2, mounted loosely on it, which lever carries a pawl, f a, which engages with the teeth of the ratchet-wheel f. The said lever f2 is jointed at f* to a rod, G, which' is also jointed to a lever, H, which is secured to the truunion a of the vessel A.

The method of using the apparatus herein.

before described and its action areas follows: The apparatus being so arranged relatively to the conduit conveying the duid to be treated co are supports on which the free ends' -that the said duid will pass into the vessel A,

been passed into the said vessel is sufficient yto overba-lance it, it turns on its pivots or trunnions and draws down the lever f 2 and pawl f3, as indicated in dotted lines in Fig. 2, and when emptied returns to its normal position, its return causing a portion of the matter contained in the hopper E to be discharged into it by the action ofv the screw F, which is partly rotated on the return of the said vessel by the engagement of the pawl f 3 with the teeth of the ratchet-wheelj". The quantity of matter discharged from the hopperE at each action of the apparatus may be increased or decreased by connecting the rod G to the lever H farther from or nearer to the axis of the latter.

Instead of mounting a screw in the hopper for regulating the passa'geof the matter therefrom, we in some cases arrange slides one above the other in the lower part of the'hopper, the lsaid slides having openings formed in them, and being so connected to the tilting,V

vessel as to be actuated as required by the motion ofthe said vessel. This arrangement is illustrated in elevation, partly .in section, 1n

` Fig. 5 of the accompanying drawings, and in plan in Fig. 6. I l are the slides, which have openings z" formed in them, and are connected by cords i2 i2 to the lever d', carrying the weight D, and by cords 'i3 i3 to a rod, a3, secured at its ends to the sides of the vessel A, the said cords passing over pulleys j j', working in bearings J J, secured to a frame K, supported by the uprights B B. This arrangement acts as follows: When the vessel A descends to discharge its contents, the space between the two slides is closed by the slide I, and the opening in the slide I is brought 4within the mouth of the hopper, a portion of the matter contained in the hopper being thus allowed to descend into the said space. On the vessel A returning to the position shown in Fig. 5 the slides are caused toreturn to the position shown in the said figure, and the portion of matter below the slide I passes through the opening 'Z' in the slide I and falls into the vessel A. The quantity of matter discharged from the hopper at each action of the apparatus may be increased or decreased by increasing or decreasing the capacity of the lower part ofthe hopper between the two slides.

In cases where the matter with which the i hopper is charged is of such a nature as to be quiring sufficient momentum to overcome the resistance of the said slides before the said cords are drawn tight. The slides are thus started with a jerk and the said resistance is overcome, the force with which the slides are acted on when startedbeing in proportion to the momentum acquired by the vessel A,

`which momentum is greater or less, according to the amount of slack in the said cords.

In Fig. 7 of the accompanying drawings another arrangement for effecting the discharge from the hopper of t-he matter contained therein isshown, the said arrangement consisting of an endless band, L, mounted below the mouth of the hopper E on rollers Z Z, the axes of which Work in bearings Zl Z2 afxed to the uprights B B, to which band the required motion is imparted bymeans of mechanism similar to that hereinbefore described with reference to Figs. 1, 2, and 8 of the accompanying drawings for working the screw F. M is a sliding plate arranged within the hopper, by raising and lowering which plate the quantity of matter passing from the hopper at each action of the apparatus may be increased or decreased, as required.

-In cases where the matter with which the hopper is charged is of such a natureas to be liable to bridge 7 therein, or not to descend when the discharging mechanism is actuated, wemount or arrange in the hopper a stirrer consisting of a rotatory shaft carrying arms, which stirrer we so connect to the tilting vessel that at each motion of the latter the said shaft isrotated or partly rotated. This arrangement is illustrated in Fig. 8 of the ac` companying drawings, in which figure Nis the rotatory shaft, and 'n' n are the arms carried thereby. The said shaft is supported by bars n n2 within the hopper, and carries at ,its upper end a pulley, O, around which passes a cord, o', which also passes over pulleys o2 o, mounted in frames secured to the hopper, and is secured at its ends tothe vessel A and counterbalance-l'ever d.

Instead of using a stirrer,we in some cases so mount the hopper that it may be capable of a vibratory motion, and we mount a hammer on or in connection with the vessel A in such a position relatively to the said hopper that at each action of the apparatus the hopper is shaken or jogged sufficiently to disturb its contents andinsure their descent as required. This arrangement is illustrated in vertical section in Fig. 9, and in plan in Fig. 10, of the accompanying drawings, in which figures PP are rods or springs secured at their lower ends to the uprights B B, and at their upper ends to the hopper, which is supported entirely by the said rods or springs P P. Q is an arm aiixed to the lower part of the hopper, and R is a hammer mounted on a spring-stem, r', secured to the side of the vessel A. By this arrangement the hopper is shaken at each action of the apparatus, the hammer R striking the arm Q each time the vessel A rises after discharging its contents. In order to limit the extent of vibration of the hopper, grooves b2 b2 are formed in the uprights B B, -in which .grooves the springsP P Work, the saidsprings vention and the manner in which the same is to be performed, we wish it to be understood that We claim as our invention, in an apparatus for use in the treatmentof sewage,and in other operations in which solid matter is required to be added to or/miXed withpiiuid matter in certain relative proportions, the following:

1. The combination of the tilting vessel or receptacle, and the hopper having adischargingscrew,with the ratchet-and-pawl mechanism,and the connecting arm and lever for actuating said'discharging-screw by the movement of. the tilting vessel, substantially as described..

2. The combination of a feed-hopper, an au- Y tomatically-operating tilting receiving-vessel having a connection therewith to automatically feed material to the receiver, an automatic agitator to the hopper, and a counterbalance to the receiver, substantially as described.
